This is a combination of probability and thought experiment.
It involves Schroedinger's Cat.
On a box a label is found :DO NOT OPEN THE BOX MIGHT ANNIHILIATE THE FUTURE.
What are the chances of finding the future?

Additional questions:
Suppose if there are N such boxes then what are chances of finding the future?

Suppose that the box has a label : OPEN THE BOX AND YOU MIGHT FIND THE CAT DEAD.
Then what are the chances of finding the cat dead if there are N boxes.

Multiverse questions>
Suppose that there are infinitude of Universes then what are the chances that a Future in some Universe was lost due to this observation?

If the multiverses interact then what are the chances of reaching from X to Y ?(Given that every possibility gets realized in some universe)

The questions are interesting because we can ask questions on logical relevance of Multiverse theory.
The Multiverse theory explains using the inescapable logic :
Because everything was possible no wonder that this happened.

But do we see the diversity and uncertainity due to Multiverse interactions???
How few are the universes and there interactions that the 10 consecutive heads are so rare???
think and respond

The only way I have been able to eliminate it completely is to drink Egg Nog (of all things) at the same time. But 1) Egg Nog is only available from Thanksgiving to New Years in my area, 2) the calories are killing me even with light versions, and 3) I think I might be lactose intolerant.

I already take a baby aspirin with it.
